人工电源网络（AMN）的校准

人工电源网络（AMN）作为电磁兼容测试中主要的陪试设备,在整个电磁兼容测试中发挥了极其重要的作用。为了减小人工电源网络（AMN）在电磁兼容测试中引入的测量误差,通过对人工电源网络的电路结构和其在测试中的用途进行了分析,文章给出了人工电源网络的阻抗特性和插入损耗的测试方法并且通过实际的测试验证了该测试方法的可行性。最后给出了减小人工电源网络（AMN）的插入损耗引起测量误差的方法并且对人工电源网络在使用中的应该注意的事项进行了说明。

Calibration of Artificial Main Networks(AMN) Used in EMC Test

The artificial main networks(AMN) which is used as the major accessory equipment in the test played a very important role in the whole EMC test.In order to reduce the measurement error injecting by the artificial main networks, an analysis are carried out through the structure and the application of the artificial main networks in the test.The test methods of the impedance characteristic and the insertion loss of the artificial main networks are put forward, and the feasibility of the methods are verified b...
